Application nea January 22, 1925. Vserial No; 3,901. l

rllhis Vinvention relates to firearms and for Athe purposeof illustration is shown as apf plied to `the firearm ofthe autoloading type, such as the arm disclosed in Patent 659,507, Oct. 9, 1900, to J. M. Browning. "f V Gunsof this type are adapted to contain a number of shells or cartridges in a magazine aswell as a shell in the chamber. When the shell in the chamber is'fired the recoil .10 of the arm is utilized for the purpose of setting in` motion devices which open Ythe breech, cock` the hammer, eject the empty shell, transfer afresh shellto the chamber, and close and lock the breech. Therec'oil spring associated with the movable breech block serves in part, to absorb the energy of the recoilV and to bring the actuated parts to rest in their rearmost position. However, in order to insure that the mechanism will ,2,0 be fully operated at all times, it is necessary to so regulate the effect ofthe recoil spring vthatthe rearwardly moving parts are moving with an appreciable velocity when they reach theirrearmost position, and a positive 'stop must be provided to 4check their movement. AIn the patent to Browning above identied, the rearwardly moving vbreech block and barrel extensionare stopped by the engagement of the barrel extension with4 the end of ythe receiver: or-frame, This ar,-

rangement is objectionable fact that the, contactingparts are both of metal, and the sharp blow which is struck againstv the stationary frame by the rearwardly moving members is unpleasantv for thel shooterand injuriousto both the frame and the mechanism. In some guns springs have been provided for stopping the `rearward movement, butsprings are objectionablebecause the energy vstored in the spring accelerates the forward movement :of 4the parts and intensifies the shock when the parts areV stopped in their forward position.

One'object of the present invention is to provide an improved buffer adapted to stop the rearward movement of thegun action Without acceleratingr its forward movement.

v AA further object` of the invention is to provide an improved retainer or holder' for a'buffer of shockdeadening material.

A further object of the invention .is to provide new and improved means for attaching a shock absorbing buffer to the frame.

by` reason of the Vith these other objectsv in view my in vention consists of the ynovel combinations and arrangements of parts which are illustratedfin th'e drawings vand will be herein after more fully described,

.In the drawings Y Fig. 1 is a fragmentary longitudinal section through a receiver of the gun of the type shown in Patent 659,507, showing `my invention applied thereto. For greater clearness many'details of the breech mechanisin have been omitted.y

Fig. 2 1s a rearview offmy improved shock absorbing buer.

Fig. 3 is a section on Fig. 2. y i y Fig. 4 is a perspective of buffer member separate from its reinforcing member,

Fig.` 5 is a front viewof a modified form of my invention.

The receiver or frame 10 of the gunl illus- Ytrated in the drawings is'adapted to contain and the breech block f the barrel extension 11 12. Suitably supported 'in the breech block 12V are the firing pin 13,' and the locking bolt 14, pivoted to the locking bolt'operating link 15. When barrel extension andthe breech block move .rearwardly to the jrear end ofthe frame. To

prevent these parts striking a sharp blow on the end of the frame by means which will not accelerate their ,forward movement, the present invention contemplates the use of a shock preventing or buffer device which. will now be described. Y

The shock preventing device comprises a disk 16 of fiber or other suitable shock deadening, substantially non-resilient material. A portion of said disk is cut away, as seen in Figs. 2 and 4, to provide a clearance for lthe locking boltand breech block operating .linklf A .kerf 17 is cut.: about the periphery off?, one. face of the disk.` A reinforcing member inthe shape of ashallow cup or container 18, preferably of metal, covers the back and edges of the buffer disk 16, and

has an inturned edge 19 which overlies the.

kerf or. recess 17. The depth of the kerf is slightly greater than the thickness of the metal ofthe container, whereby the face of the `shock deadening disk rather than the Vedge 19 of the container contacts with the rear end of the breech block and barrel eX- tension when these parts are retracted.

the line B-Srof y the gunhas been fired the e The metal reinforcing member thus constructed is of singular effectiveness in preventing the rapid destruction ofthe fiber disk by a large number of impacts of ,the breechblock and barrel extension.Y If the edge of the ber diskis left-free it soon shows atendency to separate into laminas and disintegrate, the separation beginningat the edges of the '.disk. By providing the metal container Whichiirmlyf engages the edges ofthe diskv this disintegration is prevented, and la shcckfdeadener of remarkably long' life is'secure'd, I v

,'Various means may be 'employed' for securing 'theber disk and its'container in place. The securing' device illustratedV in the drawings comprises special scre-Wsj20 AWhich 'extendlthru openings inthe backv of the 'cup 18, and Yare' received in threaded openings in thev end of the frame. The heads 2l of the screwsyQO occupy recess s 22 in ber disk 16. To facilitate tightening of screws 20 in the threaded openings;l veach of the screws which rotates-freely in its Vsupporting recesspcomprises vafslot23 in its free end, adapted to receive the bit ofa screw driverginserted thrutheI threaded opening. An'unusually convenient and'effective securingdeviceisthus providedl In Fig. 5 I have'illustrate'd a modification of --my invention in v vhic'zh'` the 'inturned flange 19 terminates adjacent v the 'sidesf of theE operating link' clearance slot, in'v place of Y pirata.
